Wait only one second at shutdown/reboot for lingering processes

Browse Source 
Transitioning to runlevel 0 or 6 handles graceful shutdown of any
managed run/task/sysv/services.  So we can replace the old 2 sec delay
with a shorter one for any non-managed still lingering process.

Also, some minor cleanup.
